Deprecation: TURN port range

告知日 廃止予定日
2019年2月27日 2019年5月31日

Effective May 31, 2019, the port range required for TURN server communication will move exclusively to 16834–32768. This range is a subset of the currently active ports (16834–32768 and 49152–65535). 



As of May 31, 2019, PureCloud’s TURN servers will stop allowing connections outside the 16834–32768 port range. Customers who have this range blocked will no longer be able to place or receive calls using WebRTC stations.


If anyone in your organization uses the PureCloud WebRTC web-based phone for Agent or Business User telephony, you may be affected by this deprecation.


Customer firewalls placed between WebRTC clients and PureCloud must be configured to allow for connectivity in the 16834–32768 port range. The upper range (49152–65535) will no longer need to be opened.
